Waves Flashcards
What is the wavelength of a wave?
It is the distance of the wave between two adjacent peaks or troughs
What is the amplitude of the wave?
It is the distance from either the trough or peak to the centre line.
What is the frequency of the wave?
It is the number of waves passing a point in one second
What is the equation for calculating the speed of the wave?
Speed = frequency x wavelength
How do transverse waves move and what are some examples?
They move up and down. These are electromagnetic and water waves
How do longitudinal waves move and what is an example?
The move forwards and backwards. These are sound waves
How are seismic waves produced?
They are produced by earthquakes and explosions
What is a Primary wave?
Slower-moving longitudinal waves.
What is a Secondary wave?
Faster-moving transverse waves.
